This week as you can see is World Glaucoma Week. As one of my aunts suffers from the condition I am delighted to share a bit more about the week with my readers.
So what is glaucoma? Well the World Glaucoma Week web site has produced an excellent definition which we would like to share with you.
“Glaucoma is a group of eye diseases that cause progressive damage of the optic nerve at the point
where it leaves the eye to carry visual information to the brain. If left untreated, most types of
glaucoma progress (because the person with glaucoma cannot see the symptoms) towards slow
worsening visual damage and possible blindness. This visual damage is mostly irreversible, and this
has led to glaucoma being described as the “sneak thief of sight”.
Glaucoma is the leading cause of irreversible blindness worldwide, yet 90% could have been
prevented. 9 million persons globally are blind from it and this number will rise as the population ages and increases
. Owing to the silent progression of the disease – at least in its early stages – up to 50%
of affected persons in developed countries are not aware of having glaucoma and are receiving no
. This number rises to 90% in less developed parts of the world. ”
To find out more about risk factors, screening and treatments please check out our blog post for National Glaucoma Awareness Month which tool place in January.
January is National Glaucoma Awareness Month, an important time to spread the word about this sight-stealing disease. The Glaucoma Research Foundation have produced the following really useful information which we would like to share.
You may also wish to read some of our previous coverage of glaucoma here.
They say “Currently, more than 2.7 million people in the United States over age 40 have glaucoma. The National Eye Institute projects this number will reach 4.2 million by 2030, a 58 percent increase.
Glaucoma is called “the sneak thief of sight” since there are no symptoms and once vision is lost, it’s permanent. As much as 40% of vision can be lost without a person noticing.
Glaucoma is the leading cause of preventable blindness. Moreover, among African American and Latino populations, glaucoma is more prevalent. Glaucoma is 6 to 8 times more common in African Americans than Caucasians.
Over 2.7 million Americans, and over 60 million people worldwide, have glaucoma. Experts estimate that half of them don’t know they have it. Combined with our aging population, we can see an epidemic of blindness looming if we don’t raise awareness about the importance of regular eye examinations to preserve vision. The World Health Organization estimates that 4.5 million people worldwide are blind due to glaucoma.
Help Raise Awareness
In the United States, approximately 120,000 are blind from glaucoma, accounting for 9% to 12% of all cases of blindness. Here are three ways you can help raise awareness:
Talk to friends and family about glaucoma. If you have glaucoma, don’t keep it a secret. Let your family members know.
There are two main types of glaucoma: primary open-angle glaucoma (POAG), and angle-closure glaucoma. These are marked by an increase of intraocular pressure (IOP), or pressure inside the eye. When optic nerve damage has occurred despite a normal IOP, this is called normal tension glaucoma. Secondary glaucoma refers to any case in which another disease causes or contributes to increased eye pressure, resulting in optic nerve damage and vision loss.
Glaucoma is the second leading cause of blindness in the world, according to the World Health Organization. In the most common form, there are virtually no symptoms. Vision loss begins with peripheral or side vision, so if you have glaucoma, you may not notice anything until significant vision is lost.
The best way to protect your sight from glaucoma is to get a comprehensive eye examination. Then, if you have glaucoma, treatment can begin immediately.
Glaucoma is the leading cause of blindness among African-Americans. And among Hispanics in older age groups, the risk of glaucoma is nearly as high as that for African-Americans. Also, siblings of persons diagnosed with glaucoma have a significantly increased risk of having glaucoma.
Are you at risk for glaucoma? Those at higher risk include people of African, Asian, and Hispanic descent. Other high-risk groups include: people over 60, family members of those already diagnosed, diabetics, and people who are severely nearsighted. Regular eye exams are especially important for those at higher risk for glaucoma, and may help to prevent unnecessary vision loss.”
